What type of illumination is recommended for photographing external eye structures?

  1. Direct

  2. Diffuse

  3. Oblique

  4. Specular

The correct answer is: Diffuse

Diffuse illumination is recommended for photographing external eye structures because it provides even lighting without producing harsh shadows or reflections. This helps to capture clear and detailed images of the external eye structures without causing any unnecessary distortions or glare. Direct illumination may create harsh shadows, oblique illumination may not evenly light the area of interest, and specular illumination may result in unwanted reflections on the eye surface, all of which can affect the quality of the photograph.
